Ok - here's my thoughts on your list so far, but read my post above
Almost all these breeds you will pay about $500 or more for a pet (neutered/spayed). The Chartreux may be higher as well as the Bobtail/Curl since they are not as common.
*Ocicat - we paid $600 for our boy (pet price) - VERY active cat, easy grooming, smart, social, gets along well with dogs, kids, people. Semi-talkative. Loves interactive playing. Will be top cat (just on principals)
Oci's do come in non-spotted patterns - classic, pointed, and ticked like the aby - because they still have the influence of the 3 breeds that created them (aby, american sh, siamese) - these non-spotted kittens still have ocicat personality and can be gotten at a much lower price - only spotted ones can be shown.
*Chartreux - laid back cat, easy grooming. fairly quiet. I've only seen a few of them in the shows and a friend back on the east coast had one they showed, so I don't know a lot about them.
*Exotic - shorthair persian. Less grooming then a normal persian, but still more then you think. Quiet but more active then their longhair cousins. Comes in a rainbow of colors/patterns.
*Persian/Himalayan - highest maintenance cat of the group - daily grooming required if you don't want them to mat! Quiet, laid back. Can act "anti-social" at times thinking they are better then everyone else
This is the "glamour" cat.
*Scottish Fold - quiet, laid back, cute, more of an American or British SH personality. The non-folded cats would be less money.
*Selkirk Rex - got to meet them at this past show - unusual fur - SHOULD be plushy and dense feeling. General grooming. Comes in SH and LH (I like the SH better). Not as active as the other rex breeds.
Siberian/Maine Coon/Nor.Forest Cat - these are very similar to each other and basically need about the same grooming - 2-3 times a week in combing to keep mats out. They are all interactive cats and fairly active. These are the bigger cats when full grown - 15+ lbs. Gets along well with other cats, dogs, kids.
*American Bobtail/Curl - I know more about the curl - they are medium size cats, come in long and short hair versians and need general maintence in grooming (the long hair more then short hair of course). Seems to adapt well to most situations and animals.
*Ragdoll/Ragamuffin - the muffins are an offshoot of the Ragdolls. - laid back, social cats, they need less grooming then most longhairs cause their coats are silky and soft and don't mat easily. Gets along well with dogs, kids, etc. However, they usually tend to be on the pricey side - $800 for pets, sometimes more. Ragdolls are more/less a pointed/bi-color cat; the Ragamuffin comes in a lot of other colors. These also wind up being large cats 15+ lbs when grown.
Thanks for the mention of the "retired" cats. This can be a good option as you still get a nice cat, but one that is full grown and more tolerate to things. Also the breeders will probably charge about half the price of a kitten on a retired cat. They want the cat to be loved and spoiled and usually only want the cost to cover vet expenses and spay/neuter and shipping. We tried to get a retired cat when looking for our Ocicat but no one had the "right" one we were looking for - so we ended up with a kitten
